Objective The Objective of this study was to explore the role and mechanism of long non-coding RNA(lncRNA)HCP5 in triple-negative breast cancer. Methods The mRNA content of HCP5 in breast cancer cell lines and normal breast cell lines was analyzed by qPCR,and the RNA Scope method was used to analyze the expression of HCP5 in breast tissues and breast cancer tissues.The effect of knocking-down HCP5 on the proliferation of triple negative breast cancer cells was analyzed by CCK-8 and cell survival/death experiments.The effect of knockdown HCP5 on the proliferative ability of breast cancer cells was analyzed in nude mice.Antibody microarray technique was used to analyze the effect of knockdown HCP5 on the expression of BIRC3 and caspase-3 proteins in the apoptotic pathway. Results Compared with normal breast cells and other types of breast cancer cells,HCP5 was up-regulated in triple negative breast cancer cell lines(P<0.05).Compared with normal breast tissues and other subtypes of breast cancers,HCP5 in triple negative breast cancer tissues were up-regulated(P<0.05).Compared with the control group,triple-negative breast cancer cells in the HCP5 knockdown group were decreased proliferation,increased apoptosis of triple negative breast cancer cells,and inhibited the growth of orthotopic tumor in nude mice(P<0.01).Knockdown of HCP5 caused a decrease expression of apoptotic inhibitor BIRC3 and an increase expression of Caspase-3 in the apoptotic pathway,the difference was statistically significant(P<0.05).There was no difference in the effect on the MAPK signaling pathway protein between wild and HCP5 knockdown groups. Conclusion lncRNA HCP5 promotes the malignant progression of triple negative breast cancer through regulating the apoptotic pathway.

Objective The aim of this study was to evaluate the effect of myasthenia gravis(MG)on the prognosis of patients with thymoma after surgery,and to analyze other related factors affecting the prognosis of patients with thymoma after surgery. Methods The clinical data of 187 thymoma patients in the 8th Medical Center of the Chinese People's Liberation Army from September 2002 to January 2018 were retrospectively analyzed.Among them,139 thymoma patients complicated with myasthenia gravis(MG group)and 48 patients with simple thymoma(non-MG group).The 1∶1 nearest neighbor matching method was used to perform propensity score matching(PSM)for the two groups to achieve equilibrium within covariance.Kaplan-Meier method was used to calculate the survival rate,and log-rank test was preformed to analyze the differences in survival rates between MG and non-MG groups.Cox proportional hazard regression model was used for univariate and multivariate analyses for overall thymoma patients after surgery. Results Before the results were matched,the gender(χ2=4.180,P=0.041),age of diagnosis(χ2=8.590,P=0.003),WHO histological subtype(χ2=4.764,P=0.029)and postoperative adjuvant chemotherapy(χ2=5.627,P=0.018)were significantly different between the MG group(n=139)and the non-MG group(n=48).The 5-year overall survival rates of patients in the MG group and non-MG group were 92.4% and 69.6%,respectively,and the difference was statistically significant(Log-rank test,P=0.002).After matching by the PSM method,a total of 44 of patients were successfully matched in the two groups,and there was no significantly difference in clinical baseline data between the MG and non-MG groups(P>0.05).The 5-year overall survival rates of patients in the MG group and non-MG group patients were 90.8% and 67.3%,respectively,and the difference was statistically significant(Log-rank test,P=0.015).Univariate analysis for patients with overall thymoma surgery showed that Masaoka stage(HR=0.237,95% CI:0.111~0.504,P<0.001),resection status(HR=0.250,95% CI:0.096~0.654,P=0.005),postoperative adjuvant chemotherapy(HR=0.367,95% CI:0.179~0.751,P=0.006)and MG(HR=0.336,95% CI:0.162~0.669,P=0.003)might be associated with survival prognosis of thymoma patients after surgery.Cox multivariate analysis showed that Masaoka stage was an independent prognostic factor affecting the survival of thymoma patients after surgery(HR=0.317,95% CI:0.140~0.720,P=0.006),and MG affected protective survival factors of thymoma patients after surgery(HR=0.445,95% CI:0.204~0.971,P=0.042). Conclusion For patients with operable thymoma,thymoma patients with MG have a better prognosis than those without MG.Masaoka stage is an independent prognostic factor that affects the survival of thymoma patients.

Lung cancer is one of the most common malignant tumors,which seriously affects people's body and mental health.In most countries around the world,its morbidity and mortality rank first,so the necessary for early screening of people at high risk for lung cancer is increasing.With the promotion and application of low-dose computed tomography(LDCT)in various countries,the mortality of lung cancer has been significantly reduced,but at the same time it has also brought many problems,such as high false positives and overdiagnosis,to cause double burden of patient economics and psychology.More and more women are passively smoking,but they are not included in the screening of high-risk lung cancer groups;The screening lung cancer for the definition and standards of high-risk pupolation as well as the definition and standard of positive nodules have not yet been unified guideline release,etc.These issues are becoming increasingly prominent,and today many studies are facing the main difficulties and challenges.This article reviews the research status and progress of LDCT in lung cancer screening.

Breast cancer is a heterogeneous systemic disease.Its microenvironment is mainly composed of tumor cells and a variety of non-tumor cells.Among them,mesenchymal stem cells(MSCs)play an important role in tumorigenesis and development.MSCs can interact with tumor cells and their microenvironment directly through gap junctions,membrane receptors and microtubules,or indirectly through soluble molecules.Tumor-associated fibroblasts(CAFs)are derived from adjacent cancer fibroblasts or MSCs,and play an important role in tumor drug resistance.In breast cancer,tumor stem cells and their microenvironment are in a dynamic equilibrium state,and their phenotype is closely regulated by cytokines.Interstitial cells have an important effect on their biological characteristics through their interaction with breast cancer cells.In addition,interstitial cells can change the sensitivity of tumor cells to chemotherapeutic drugs,which in turn make them resistant.Therefore,addressing tumor stromal cell-mediated resistance to chemotherapy is the key to successful treatment of advanced breast cancer.This article mainly describes the research progress of stromal cells in the microenvironment mediated chemotherapy resistance of breast cancer.
